disk, excentric ; filaments free ; anthers introrse. Germen excentric, 

 3-locular ; style slender, stigmatose 3 -fid at apex ; ovules in cells 

 solitnry ascendent from the base of the internal angle ; micropyle 

 extrorsely inferior. Capsule membranous, 3-gonal ; cells inflated, 

 produced upwards at the back to a vertical wing, finally free from 

 axis and dehiscing longitudinally inwardly and at the apex ; seed 

 subglobose, exarillate ; testa hard ; cotyledons of exalbuminous 

 curved embryo 2-plicate. — An erect glabrous shrub ; leaves alternate 

 coriaceous, entire or 3-lobed, dentate and iuciso-serrate ; flowers 

 axillary pedunculate, solitary or 2 or few cymose. {Chili}) 



54. Urvillea H. B. K.^ — Flowers irregular polygamo-dicecious 

 (nearly of Paullinia) ; sepals 5, unequal, imbricate ; the two ex- 

 terior smaller. Petals 4, furnished with squamule within, imbricate. 

 Stamens 8, interior to 1-lateral disk, unequally distended into lobes 

 or disconnected glandules. Excentric germen and ovules of Paul- 

 linia; style short, stigmatose o-fid at apex. Fruit 3 samarse, to 

 middle seminiferous membranous broad winged, indehiscent and 

 finally free from short central columella. Seeds arillate at base; 

 testa crustaceous ; cotyledons of exalbuminous embryo thick. — 

 Scandent or volubile shrubs, sometimes cirriferous ; leaves alternate 

 stipulate ternate ; leaflets -entire or dentate, sometimes punctate ; 

 flowers in axillary shortly cymiferous racemes 2-cirrose at base. {Both 

 Tropical Americas}) 



55. Serjania Plum.^ — Flowers polygamous irregular (of Urvillea) ; 

 fruit 3 samara3, indehiscent, seminiferous at apex. Other characters 

 of Urvillea. — Scandent or volubile shrubs ; leaves alternate, 3-nate, 

 2-ternate or imparipinnate, often punctate ; inflorescence of Urvillea, 

 {Tropical and Suhtropical South America^')
